[Epidemic situation of human echinococcosis in Inner Mongolia Autonomous Region: a sampling survey from 2012 to 2017].

OBJECTIVE: To investigate the epidemiological characteristics of human echinococcosis in Inner Mongolia Autonomous Region, so as to provide evidence for the development of the precision control strategy of human echinococcosis in the region. METHODS: A sampling survey of human echinococcosis was conducted in 28 banners (counties, districts) of Inner Mongolia Autonomous Region from 2012 to 2017, and the epidemiological characteristics were descriptively analyzed. RESULTS: A total of 90 058 residents were examined for echinococcosis in 28 banners (counties, districts) of Inner Mongolia Autonomous Region from 2012 to 2017, and 71 patients were detected with echinococcosis, with a detection rate of 0.08%. No echinococcosis cases were identified in 8 banners (counties), and there were 6 banners (counties) with echinococcosis prevalence of 0.1% to 1%, and 14 with prevalence of 0 to 0.1%. The echinococcosis prevalence was significantly greater in women (0.11%) than in men (0.05%) (χ2 = 10.09, P = 0.001), and the highest prevalence was detected in patients at ages of over 50 years (38 cases, 53.52%). In addition, the highest echinococcosis prevalence was detected in herdsmen (0.14%), or in primary school children (0.13%). CONCLUSIONS: Human echinococcosis is widely, but lowly prevalent in Inner Mongolia Region, with a diverse density of infections. Echinococcosis has remarkable characteristics of regional and population clusters in Inner Mongolia Region, and the management of echinococcosis requires to be reinforced in key regions and populations.

[Spatial distribution characteristics of reported echinococcosis patients in Inner Mongolia Autonomous Region from 2013 to 2018].

OBJECTIVE: To investigate the spatial distribution patterns and changing tendency of reported echinococcosis patients in Inner Mongolia Autonomous Region from 2013 to 2018, so as to provide the evidence for the management of echinococcosis in high-risk areas. METHODS: All data pertaining to echinococcosis patients in Inner Mongolia Autonomous Region were captured from the National Notifiable Communicable Disease Reporting System from 2013 to 2018 and analyzed using a spatial epidemiological method. RESULTS: The incidence of reported echinococcosis was 0.22 to 0.41 per 100 000 in Inner Mongolia Autonomous Region from 2013 to 2018, and the number of banner reporting echinococcosis patients increased from 24 in 2013 to 39 in 2018. The highly prevalent areas of echinococcosis were mainly concentrated in West Ujimqin Banner (the highest incidence, 19.23 per 100 000), East Ujimqin Banner (the highest incidence, 12.93 per 100 000) and New Barag Right Banner (the highest incidence, 11.66 per 100 000). Three-dimensional trend analysis showed that the areas with high incidence of reported echinococcosis were mainly located in central by eastern parts of Inner Mongolia Autonomous Region. There was a positive spatial autocorrelation in the number of echinococcosis patients, and the cases appeared a clustering distribution (Moran's I > 0, P < 0.05), with "high-high" and "low-high" regions. CONCLUSIONS: The reported echinococcosis patients show a spatial aggregation in Inner Mongolia Autonomous Region, and the hotspot areas are mainly concentrated in Xilingol League and Chifeng City, in which targeted control interventions for Inner Mongolia Autonomous Region are recommended to be intensified.

[The current situation of ophthalmologic examination and treatment of diabetic patients in a community of Fushun].

Objective: To investigate the attainment of therapeutic targets for glycosylated hemoglobin and blood pressure, ophthalmologic examination, diagnosis and treatment of diabetic retinopathy (DR) with type 2 diabetes mellitus. Methods: A cross-sectional study in type 2 diabetic patients was conducted in a community of Fushun between July 2012 and May 2013. Questionnaire, detailed ophthalmic examination and laboratory tests were completed to collect the information about sociodemographic and healthcare characteristics. Results: A total of 2 033 eligible patients with complete information were screened from 2 224 type 2 diabetic patients. Of them, the control rates of glycosylated hemoglobin(<7.0%), blood pressure[<140/80 mmHg (1 mmHg=0.133 kPa)] and serum lipid were 39.7%, 31.0% and 2.6%, respectively. Only 22.3% of the participants had ophthalmologic examination after the diagnosis of diabetes mellitus, and 72.2% of the participants in the study reported never receiving any recommendation for eye examinations from their physicians. The prevalence of DR was 44.3% in the study population, 27.1% receiving ophthalmologic examination ever. Among them, 213 patients had vision-threatening DR and required laser treatment or vitreous surgery, but 82.2% had not been treated. Conclusions: The investigation of the type 2 diabetic patients in a community of Fushun indicated that more than 60% of patients did not attain therapeutic targets for glycosylated hemoglobin, and 70% for blood pressure; 78% had not received ophthalmologic examination after the diagnosis of diabetes mellitus; 82% of vision-threatening DR patients had not been treated. Educational efforts should be aimed at improving knowledge of and compliance with these guidelines among both internists and eye care providers. (Chin J Ophthalmol, 2018, 54: 599-604).

[Changing patterns of surgical treatment for glaucoma in the Eye Hospital of Wenzhou Medical University during the past ten years].

Objective: To investigate the patterns of surgical treatment for patients with glaucoma in the Eye Hospital of Wenzhou Medical University from 2005 to 2014. Methods: Retrospective case series about 6 781 glaucoma patients (7 751 eyes) who received surgical treatment from January 1, 2005 to December 31, 2014 in the Eye Hospital of Wenzhou Medical University. Among them, 2 869 were males and 3 912 were females, aged (62±14) years. The data of patients' demographic information, diagnosis and surgical procedures [trabeculectomy, aqueous shunts of ExPRESS and Ahmed for extraocular reservoir, cataract extraction with intraocular lens (IOL) implantation, and combined operations for glaucoma and cataract] were collected and the patterns of surgical treatment were evaluated. SPSS 21.0 statistical software was used, mainly for statistical description of the data. Results: The ratio of trabeculectomies increased between 2005 and 2009, from 48.2% (95/197) to 57.7% (488/846), but decreased to 21.1% (220/1 041) in 2014. The ratio of aqueous shunts of ExPRESS and Ahmed increased to 6.1% (63/1 041) and 7.6% (79/1 041) from 2005 to 2014, respectively. The ratio of cataract extraction with IOL implantation increased to 28.4% (294/1 036) in 2012, but decreased to 21.6% (225/1 041) in 2014. The ratio of combined operations for glaucoma and cataract decreased to 6.6% (47/717) from 2005 to 2010, and increased to 36.6% (381/1 041) in 2014. Over the decade, the ratio of cataract extraction with goniosynechialysis increased from 2.4% (15/623) to 17.7% (184/1 041). The rate of iridotectomy decreased to 0.2% (2/1041) in 2014. Conclusions: Trabeculectomy, cataract surgery and combined surgery for glaucoma with cataract were still the mainstream of glaucoma surgery in the Eye Hospital of Wenzhou Medical University from 2005 to 2014. And the ratio of cataract extraction with IOL implantation, aqueous shunts of ExPRESS and Ahmed, and combined operation for glaucoma and cataract rapidly increased, with cataract extraction with goniosynechialysis increasing most rapidly and becoming the mainstream procedure of treatment for glaucoma and cataract. Inversely, the rate of trabeculectomies and iridotectomies decreased dramatically over this period.(Chin J Ophthalmol, 2018, 54: 184-188).
